Question

The speed of the bus and the time it takes are in ----------- proportion.​

Answer 1

The speed of the bus and the time it takes are in inverse proportion.

Step-by-step explanation:

We know that, if $s$ be the speed of a vehicle, in which the vehicle covers a distance $d$ in time $t$, then

$\quad \boxed{speed=\dfrac{distance}{time}}$

$\Rightarrow s=\dfrac{d}{t}$

When the covered distance $d$ is constant, we can write

$\quad \boxed{s\propto \dfrac{1}{t}}$

That is, the speed of a vehicle and the time it takes are in inverse proportion.

What does inverse proportion suggest?

• If time is changed, the speed of the vehicle will also change.
• That is, when time is increased, speed decreases.
• And when time is decreased, speed increases.
